The volume of the shaded region is 1650 cubic feet.
$300÷24 pairs of shoes is= $12.50
$12.50 = one pair of shoes
so now $12.50 × 36 = $450
Assume the number we are looking for in n
we want to know the value of n that makes 1/7 divided by n is 14
Transforming this to an equation:
(1/7) / n = 14
this means that:
1/7 = 14n
1 = 7 x 14n
1 = 98n
n = 1/98
Therefore:
1/7 divided by 1/98 will give us 14
12,24,36,48,60,72,84,96,108
Amount earned in one hour : 6.25
Amount needed to earn : 400
So, number of hours required for earning the required amount :
= Needed amount/Amount earned in an hour
= 400/6.25 = 64
